Wired and wireless earset

Abstract

The present disclosure relates to a wired and wireless earset, the earset comprising: a first earphone unit configured to be able to be inserted into a first external auditory canal of a user; a second earphone unit configured to be able to be inserted into a second external auditory canal of the user; and a main body connected to the first earphone unit, the second earphone unit and an external device, the main body comprising a switch setting up an operating mode to allow the earset to operate in one of a first mode and a second mode, and first and second speaker output adjusting circuits adjusting respective outputs of the first and second speakers in the first mode.

What is claimed is: 
     
         1 . A wired and wireless earset, the earset comprising:
 a first earphone unit configured to be able to be inserted into a first external auditory canal of a user, the first earphone unit comprising a first speaker outputting an acoustic signal or a voice signal provided from an external device, and a first microphone receiving a user voice signal provided via the first external auditory canal of the user;   a second earphone unit configured to be able to be inserted into a second external auditory canal of the user, the second earphone unit comprising a second speaker outputting an acoustic signal or a voice signal provided from an external device; and   a main body connected to the first earphone unit, the second earphone unit and an external device, the main body comprising a switch setting up an operating mode to allow the earset to operate in one of a first mode and a second mode, first and second speaker output adjusting circuits adjusting respective outputs of the first and second speakers in the first mode, and a second microphone receiving a user voice signal provided from the mouth of the user,   wherein the first microphone operates in the first mode and does not operate in the second mode,   wherein the first and second speaker output adjusting circuits address the imbalance caused by the first microphone between the outputs of the first and second speakers in the first mode by adjusting the outputs of the first and second speakers in the first mode to be reduced, respectively.   
     
     
         2 . The earset of  claim 3 , wherein the outputs of the first and second speakers in the first mode are adjusted by the first and second speaker output adjusting circuits to be reduced as compared to outputs of the first and second speakers in the second mode, respectively. 
     
     
         3 . The earset of  claim 1 , wherein the first and second speaker output adjusting circuits are configured of resistors having the same magnitude. 
     
     
         4 . The earset of  claim 1 , wherein the second microphone comprises first and second terminals,
 the first terminal and the second terminal are connected to one another via the resistor, and the second terminal is a ground terminal.
